使用 python 从文件发送 HTMLbody

我可以发送纯文本，但无法发送 html 格式的 html 文本。

import email, smtplib, ssl
import os
from email import encoders
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

body = """
this is first mail by using python
"""
port_email = 587
smtp_server = "smtp.gmail.com"
password = "your password"


subject = "An email with attachment from Python"
sender_email = "[email protected] /cdn-cgi/l/email-protection"
receiver_email = "[email protected] /cdn-cgi/l/email-protection"

# Create a multipart message and set headers
message = MIMEMultipart()
message["From"] = sender_email
message["To"] = receiver_email
message["Subject"] = subject
message["Bcc"] = receiver_email  # Recommended for mass emails

# Add body to email
message.attach(MIMEText(body, "plain"))
filename = "file name"  # In same directory as script

with open(filename.html, 'r', encoding="utf-8") as attachment:
    part1 = attachment.read()

part2 = MIMEText(part1, "html")
message.attach(part2)
text = message.as_string()

context = ssl.create_default_context()
with smtplib.SMTP_SSL(smtp_server, 465 , context=context) as server:
    server.login(sender_email, password)
    server.sendmail(sender_email, receiver_email, text)

这将发送附件，但我想查看电子邮件正文中的 html 文本。 文件名是内容 html 表，因此代码应该发送 html 文本，该文本将自动在带有 html 表的 html 正文中可用。

如果这不是你想要的，你为什么要传递一个假尸体？

您的代码似乎是为 Python 3.5 或更早版本编写的。这email库在 3.6 中进行了彻底修改，现在更加通用和逻辑化。可能会扔掉你拥有的并重新开始的例子来自email文档。 https://docs.python.org/3/library/email.examples.html

这是一个简短的尝试。

from email.message import EmailMessage

... 
message = EmailMessage()
message["From"] = sender_email
message["To"] = receiver_email
message["Subject"] = subject
# No point in using Bcc if the recipient is already in To:

with open(filename) as fp:
    message.set_content(fp.read(), 'html')

# no need for a context if you are just using the default SSL
with smtplib.SMTP_SSL(smtp_server, 465) as server:
    server.login(sender_email, password)
    # Prefer the modern send_message method
    server.send_message(message)

如果您想以纯文本和 HTML 形式发送消息，链接的示例将向您展示如何调整代码来实现这一点，但实际上，text/plain正文部分实际上应该包含有用的消息，而不仅仅是占位符。

正如代码中注释的那样，没有理由使用Bcc:如果您已经在邮件中指定了收件人To:标头。如果你想使用Bcc:你必须在其中放入其他东西To:标头，通常是您自己的地址或地址列表，例如:undisclosed-recipients;

顺便说一句，打开文件时，Python（或者实际上是操作系统）会检查用户当前的工作目录，而不是加载 Python 脚本的目录。也许还可以看到当前工作目录到底是什么？ https://stackoverflow.com/questions/45591428/what-exactly-is-current-working-directory
